Phase II trial of carboplatin in patients with advanced melanoma.

We report the results of a phase II evaluation of carboplatin (CBDCA) in 45 patients with advanced malignant melanoma. Of the 43 evaluable patients, 6 had been treated previously with chemotherapy; 11 had been treated with immunotherapy. The initial dose was 400 mg/m2 i.v. every 4 weeks; the dose was modified as required to achieve moderate myelosuppression. There was one complete response (duration 16 months) and six partial responses, for a major objective response rate of 16%. Toxicity consisted primarily of acute nausea and vomiting, and thrombocytopenia. The activity of CBDCA in this disease is similar to that of cisplatin and dacarbazine.
